Divers Penny Bielich and Heikki Innanen were scuba diving in the right place at the right time (with a camera filming, too) when a Megamouth shark happened to swim by. The divers were visiting Komodo National Park in Indonesia aboard the Samata Luxury Liveaboard and diving at the Shotgun dive site. Bielich captured the incredible footage on his camera. They estimate that the shark was 5 meters long.
